Married pair Joseph and Travis DaSilva were left facing five years in a Thai prison after their cheeky snap caused outrage

Joseph, 38, and 36-year-old Travis, both from California, were nabbed as they tried to flee the country via Bangkok's Don Mueang Airport after their photo went viral.

The offending snap was posted on @travelling_butts, which follows the couple's adventures and bare bottoms around the globe.

District police chief Jaruphat Thongkomol told Reuters: "The two American citizens have admitted taking the pictures."

The San Diego-based couple were fined £114 and processed for deportation - but could face jail instead after cops realised they breached Thailand's Computer Crime Act, which bans pornographic pictures from being uploaded to the internet.
